Description

An adjustable-speed injection molding machine based on intelligent temperature control

Technical field

The invention relates to the technical field of injection molding machines, specifically an adjustable-speed injection molding machine based on intelligent temperature control.

Background technique

Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastic or thermosetting plastics into plastic products of various shapes using plastic molding molds. There will be many problems during the injection molding process.

First of all, when the injection speed is slow, the injection speed is of great significance for some products with complex shapes, large changes in thickness, long processes, and plastics with high viscosity such as toughening, ABS, etc. When high pressure is used, it cannot be fully filled. When the injection speed is too fast, the opening force on the mold increases due to high pressure and high speed, resulting in overflow. The injection speed and injection time should be adjusted according to the thickness of the product. Thin products should be molded quickly at high speed and no more injection after fullness; thick products should be filled at low speed and the skin should be roughly fixed before reaching the final pressure, so it is reasonable. The injection is conducive to the ideal filling of the melt, and the ears are very important for improving the surface quality of the product and reducing dimensional tolerances.

The pressure of the mold injection molding machine is easily too high, and the injection time is easily set too slowly or too fast. This is a problem that many machine adjusters are not easily aware of, so the mold is easily damaged. The phenomenon of welding lines occurs. The reason for the occurrence of welding lines in products is usually due to the fact that when two or more raw materials from different directions meet, the front end part has cooled and cannot be completely fused at the joint. This is generally a defect in the appearance of the product. In this case, it mainly affects the appearance of the product and affects coating and electroplating. In severe cases, it will have an impact on the strength of the product, especially when using fiber-reinforced resin. Therefore, attention needs to be paid to the pressure of the mold injection molding machine and the injection time.

This device is adjusted through the gap between the conical check ring and the annular plug, because it can make a backflow gap exist between the conical check ring and the annular plug, unlike today's injection molding devices that do not have a pressure leakage port , so when the high-pressure injection speed of the injection molding machine is too fast, it is easy to cause overflow, and this device can well return the excess pressure from the leakage port between the conical check ring and the annular plug, so it will It gives the tuner an appropriate fault tolerance range and makes it easier for the tuner to debug.

At this time, the conical check ring 19 is no longer engaged with the annular block 16. Therefore, when the conical piston 12 pushes the material in front for injection, the conical check ring 19 is no longer in contact with the annular block 16. It is engaged with the annular blocking block 16. During the process of pushing the material, the material will flow back from the gap between the conical check ring 19 and the annular blocking block 16, so the speed of the pushed material will be slowed down. When the rotating support column 10 rotates The spiral transmission piece 11 is driven to drive the conical piston 12 to rotate. At the same time, the spiral transmission piece 11 introduces the hot-melted material into the inside of the guide groove 13, and the material pushes the conical check ring through the guide groove 13. 19 is separated from the annular plug 16, so that the inside of the guide groove 13 is led to the inside of the guide cavity 8.
